I need a battery bank to power a mini fridge 1.3 amps @ 120v for 48 hours and a electric blanket 200 watts @120v 8 hours as well as computer and cell phone charging, how many Ah will I need?
T-105s here are going for about $163 US. (using 71 cent dollars) I chose rebranded East Penn GC15s at about $124, which AFAIK are a quality battery. Perhaps there are rebranded or actual brand GC15s in your area for a good price.
You can tell GC15s even if rebranded by having the same specs as a GC15 by size , weight, and 230AH.
